Hello everyone. I have a HP Pavillion N5415 with a pci post on it. My question is this: Is there a USB 2.0 interface that will plug into this port to allow me to use some of the USB 2 devices that are available, such as a cd-rw? Thanks in advance for any help or advice. :) :) :)

You can find PCI slot cards for USB2 out there But you may also want to look at Firewire and ATA serial cards for that PCI slot
They are more reliable than USB

PCI to USB is possible and supports data transfer rates from 1.2 Mbps to 480 Mbps. Also IEEE 1394 with A and B versions stive to provide much more data transfer rates.
